Conformal Coating

Conformal coating material is a thin acrylic film which ‘conforms’ to the contours of a printed circuit board to protect the board’s components. Typically applied at 25-250 μm (micrometers) it is applied to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes that, if uncoated (non-protected), could result in damage or failure of the electronics to function
